so i have pull started it wice know it runs fine but once its off it wont start again. so it wass all stock but been working on it for almost 2 years so its fully rebuilt weber 48 ida msd blasters stock distributor with working pods. what i dont have on it yet is a fuel pressure regulator so it runs really rich and the gass is really old besides tha i think the starter is begining to die, could thoose 3 reasons be why it wont start with the key

 

I would definitely change the gas,do you have the timing set right? Is the engine rebuilt or just the carb?is wouldn't have tried to start it with old gas,that could mess things up in the carb

 

ive been thinking alot about the gas but timing is set to the sock setting both the engine and carb are rebuilt new battery stock starte. its bridge ported, i read on racing beat that its suposed to be set at 5 btdc but i haven done that yet because it has the gilmer pulley wich has no marks other than the one i made

 

so the carb wass getting very over flooded. we instaled the low presure regulator at 2 psi and this time it ran better, almost zero smoke coming out the exaust and it wass iddling on its own. so i pull up to the house and it turned off while i wass mesing with the clutch. so i tried to start it by key and like always it wont start. we looked at the spark plugs and this time they were dry the other times they were wet

 

You should test compression

 

2 psi is a sounds a bit low try 3-4 psi that might be why it shut off (not getting enough fuel) and thats why the plugs were a dry.

did it start off the key when you put the regulator in or did you have to tow start it?

 

When compression starts to drop, either through age or from flooding, you need a strong battery, a good starter, and solid grounds and positive leads to spin it fast enough to build the proper startup configuration. Tow starting covers up a lot of bad items, because it spins the engine fast enough to start in spite of bad battery, starter, or wiring.

Quick test, but run a few tablespoons of Marvel Mystery Oil down the intake and give it a few min to settle into the chambers. Start the engine with the key and if it fires, it indicates low compression. The oil helps the seals to hold compression, which helps you rule out a bad starter, battery, grounds, or positive lead. If nothing is different, or the starter speed is SLOWER, then start looking at battery, starter, and wiring.

 

it started of the key but a hard start. i think the starter is not helping much but the new gass made it start with the key i guess a new starter is up next right after cheking compresion

 

Also check or just replace the battery cables.

 

so it only wants to start with oil and the stock pump only puts out two pounds. i havent ben able to check compresion yet but the first time i did they were both at 75 i guess used housings arent the best thing to use on a rebuild

 

Looks like you found the issue. Not sure how many miles you have on the rebuild it it might get better over time.

 

im guessing thats the issue. it only has the pull start miles on it before that it was like 150 thousand. so i did the compresion test one housing went up to 100 the other one kept changing. so im waiting on the new starter so i can get a consisten starter speed
