Allright, I just put on a racing beat system, header - muffler, and hadto remove the intake to do so. I just put the intake back on as I was waiting for a new gasket. My problem now is that it will not start, the engine turns but never catches. There is a spark and if I crank and crank some more I do not smell any gas in the exhaust, what could be the problem? The float window is filling 1/2 way up with gas. This is a 1980.

peejay

try starting fluid?

kotkovetz

ok just tried that, and i could smell it in exhaust..............??? no kick tho, just turnin, one thing, looking from the drivers side, is the trailing the one on the right? if so then I have those swapped, but its worked like that before?

kotkovetz

Ok, like a good lil boy I searched and answered my plug q, I used a bit more starting fluid and it allmost seemed like it was about to catch but no go, I had the intake+carb in some weird angles, is there a chance I messed something up?

peejay

i had one time where one of the float bowls stuck open, that caused the engine to fill with gasoline

The trailing plugs are the ones on top, leading plugs on bottom... hmm... I dunno, either it's getting no spark or it's getting no fuel, assuming compression is good (it should be)

kotkovetz

well I checked one plug and it was getting a spark, it was working last monday, i dont seem to smell very much gas at all, could it just be i just gotta keep trying every 20 mins to get it all set right?

kotkovetz

it would not have to do with removing the acv and that little boingy thing right inside underneath it and blocking it off? or by blocking off the little hole to the left of the intake manifold? could it be a vacuum leak?

r u sure your getting gas, i fried my pump relay while trying to start mine on a cold day last week,, have you poured some raw gas down the throat with full choke and pumping it alot and then try starting it,,,might need a fresh battery charge pretty soon,,,dont give up,,if u dont smell alot of gas its not flooded yet,,,,,,,,,,good luck,,,,,,,

kotkovetz

yes it is getting gas and I can hear the pump, i just noticed something that i do _NOT_ like, it appears that the carb gasket looks wet from gas all around where it seals, this does not seem good...... it allmost seems like it wants to start but it wont?? i'll the the gas thing tomorrow if it doesnt start again, as for how I like the racing beat system yet I dunno hehe

DONNA

i rebuilt my carb and reset the floats and when i put the carb top back on the floats were stuck and i over flowed, tapped the top of carb with a screw driver several times and the floats fell in position,,,,,,,dont give up,,,,,,,i want to know how u like the rb,,,,,,,,,,,,,,good luck again........

kotkovetz

but if thelil gas window is getting exactly half way up as it should then the float are fine as well?

DONNA

half way in the window is good, but doesnt make sense the gasket being wet, well im as stumped as u now,,might have to go back to the vacuum leak scenario once again,,,,,,,,,can u think of anything else that u may have done while waiting for the rb,,,thats my problem, i mess with two or three things at once and then try to back track on what i did if something works worse.......youll get there, might want to let it go for a while, somethimes u got to walk away and regroup........later,,,,,,,

I just took the intake off, put it down and cleaned the intake part off (old gasket).... it was in 10 different angles... I have one looong silcon hose on the back side of the carb that I havent a clue where goes, it stretches all the way to the opposite side of the engine bay, i found a plug not plugged in, it seemed to help a little?

DONNA

haynes manual shows a good hose picture, helped me when i had rerouted some hoses wrong,,,damn hoses,,,,that long one sounds like the cruise control one on mine, not sure thou,,,,,,,,,

kotkovetz

dang if I just had cruise control I could plug that in

Keaponlaffen

The long one might be the vacuum boost for the brakes...

When I was messing around under the hood of mine, I knocked some hoses off. I just used the sticker diagram that Mazda put on the car thats convienantly located on the underside of my hood . I guess I was just to lazy to go get the manual .

I got it started and the interior looks as sweet as the car is sounding now I love every bit of it, and for some reason tho, it is _Very_ hard to start.

Umm...Well my car was running nice and was starting fine until I let it sit for about a month, and then magically it was hard to start again...I looked for ripped hoses and vaccuum leaks and sure enough I found one. It was under the carborator area, down by the manifold. It looked like the manifold had heated up too much and melted the rubber hose which eventually cause it to rip. I just used electrical tape to temporarily fix the rip. Now my car has sat for about two and half weeks and it fired right up. The hose im referring to was about an inch around. Just check for some vaccuum leaks, maybe theres something you missed. Hope that helps you.

PS - To this day I still dont know what that stupid hose does

why_pistons

does this hose run down to your exhaust pipe cause it sounds like your air pump hose

RotorMotorDriver

It could be...would that affect the starting? Like exhaust backpressure or something?

peejay

shouldn't. besides '80 didn't use any rubber hoses in the air injection circuit after the ACV - a hard metal pipe went from the ACV (actually routed through the intake manifold first) down to the heat exchanger. From there it went through the downpipe to the thermal reactor - the downpipe was a pipe within a pipe and the air from the heat exchanger went through the outside layer to get it even hotter before it actually got injected into the thermal reactor.

i'd say make sure you have no vacuum leaks of any type... either at the blockoff plates or anywhere else. hmm - when you removed the brake booster hose, did you remove the hose from the fitting or did you unbolt the fitting from the manifold?

kotkovetz

actually I cant seem to find any booster brake hose and the hose I was talking about went to the cold start assist fluid resivour. It seems to start up allot better now this nice semi-cold warming, started right up like she always did the air pump is an interesting feature with a hose from the air intake and then an open air pump, sounds... different!
