rx7 s3 questions
tl;dr got a rx7 lined up for tomorrow or thursday and need advice, it has low compression, but can be manually started, it can be driven to get compression back up (apparently), oil isnt connected to carby and is running premix fuel.
that, is the new twitch mobile, potentially, i just got off the phone with the owner, he said that it has a) low compression and wont key start, but will pull/clutch or any other form of manual start, b) it just needs to go for a long drive (100-150kms) to get the compression back up to a point where i can start it c) the oil lines arent connected to the carby (they are to the pump and everything else) carby has been clampped/blocked so there is no air bubbles, the brakes and body are in good nick, bit of rust on the body, in the sills where the normal bits are, nothing major or defectable and easily repariable, the owner has let the rego run out, but not expire (woo weird perth rules) and hence does not need a pit report (thank ****) its been bridgeported from a rx4 13b, and finally, he is running pre mix, in a 40 litre tank, at 100mls to a full tank, does that ratio sound right, or should it be increased/decreased, he said something about the oil pump being one that draws oil from the sump (cant remember its name/type lol)

Low compression means low compression. Unless the reason for low compression was sitting or flooding, then driving it won't help. Low compression means worn apex seals and/or rotor housings.

it has been sitting, could it potentially be carbon build up of some sort or another? It has just been re built he said, what about the oil fuel mix, i have heard, from my own research that 2 stroke oil is the way to go, the car has a 40 litre tank on it, so what sort of ratio should i use? what sort of effort/cost am i looking at for repairs/parts?
