Med Center Z

Seems that my I-phone 5 wont attach the video. I put it on you tube Chanel here is the link. I don't think the motor was at TDC when took the Oil Pump out and changed the Oil drive and gear.

Still having the same issue I think a leak down test is next. Here is a short video. I checked valve lash its fine. also if its relevant behind the crank pulley there is a small medal backing plate that is loose witch is concerning to me..

Hostory My z sat for 8 months in my garage. Installed 40mm webers H7 models (completely overhualed). Installed rx7 fuel pump (producing 4psi on gauge). Installed 81 280zx distributer. (Replace oil driver and gear) If relevant this is a 3.1 l28 with a V07 crank, Cam - 290/.505, 266/.490, F54/P90 Took spark plug on cylinder one out and set motor to TDC, checked to see if cylinder one is at the top of the block deck and it is. First two Cam lobs are upright on both sides and valves are closed. Motor tries to start but won't. I did a conpression test and I can't get conpression over 70 on any cylinder. I addvanced my timing to 50 degrees and the motor will idle. I'm stumped and frustrated...

Well I did a compression check and I have no compression above 70..... I don't think that's a good thing ?

How is this possible to not use a return fuel line ? How do the carburetors operate when the fuel pump is constantly fluffing the bowls with fuel wouldn't the carbs get to much fuel ? And it seems to me that running the return would benefit in reducing the temperatures of the fuel resulting in a better burn resulting in more HP/TQ Educate me....

No cold start on my n42 manifold it's shaved and has all egr equipment deleted. Oil change and plug change for sure !

I pulled my intercooler of today, I found that it was quite heavier then I remember. I Poured 1 gal of gas out of my intercooler. I have been having issues with my 3.0 stroker not getting spark, I would try and try to start it but I wouldn't fire up. I suspect that I Flooded the cylinder walls in the fuel backed up so much that it ran through the intake Plenum through the throttle body through the intercooler piping and down into the intercooler. I think I'm happy it did not start....

Wow t9 really messed up some spelling. Lets start over. I want a set of 44 or 45 mm triples. Seriouse buyer no junk no scams. I just buaght a set of weber 40 mm triples and want a bigger set for the future builds.

I want a set of 44-45 mm triples. I just bight a set of weber 40 mm triples. Seriouse buyer no joke no scams. PayPal is the way I pay and ever item needs to be insured.

I'm reading throughout sever LS forms that several people are lowering the PSI on the Walbro 255 and having no issues. They are using carb's and running 5-6 PSI all day on a regulator.

Thanks for the input.

I have a set of weber 40mm carbs that I'm using on my 3.0 l series. I currently have a walbro 255 inline fuel pump on my 240z running to a aromotive fuel regulator(with fuel pressure gauge). I have been reading that the first gen 79-83 rx7 fuel pump is a common swap while using carbs. I also found that the rx7 pump produces 3.7-4.7 psi. The question is can I regulate my walbro using my current regulator to let's say 5 psi give or take or will this damage the walbro 255 ? I hate to have to buy a new fuel pump all over again.

No thanks, still looking.

I'm I'n the market for a 1981 N/A distributer. Part must be in good condition and in working order. No scams.

Not interested in Stock carbs. Solex mikuni Webers 40MM or 44MM Please don't sell me any junk they need to be in good condition.
