Saito .80 Starting Problems
I can only get my Saito .80 to burn fuel in carb after priming and then it dies.
Engine bought used on RCU 18 months ago. Engine ran fine in April 2003 but I havn't been able to get it to run since then. Matter of fact I have never been able to get it to run since I bought it. My instructor got it running but I have tried and tried since then to no avail.
I took it to field this afternoon but nobody was there.
I have high speed needle out 4 turns and using Power Master YS 20/20 fuel with engine mounted upright. No leaks in fuel system. New filter.
Any help appreciated.

You've heard it all before. Make sure the tank and fuel lines are all set up properly, with no leaks. Prop the throttle wide open and check the complete fuel system. Pull the pressure line from the muffler, pump fuel directly into it. Stop when you see fuel running out of the carb. If you don't get fuel out of the carb find the restriction or clog. The fuel running out shows everything is clear. And any leaks should show with the pressure from your pump.
As for the starting. I have never had a satisfactory cold start of a Saito engine at idle throttle. They just wont start that way. Sputter and pop, burn off the prime, yes. But not run.
But I have never had one that didn't start like a champ with a slobbery prime at about 1/4 throttle. A lesson I had to learn. Try it, that closed throttle may be your problem too.

Bill,
I'm priming by opening throttle, placing finger over end of muffler and pulling prop though until I see fuel in line going into carb. Then throttle back about 1/2 to 3/4(plane is restrained) and use starter. Starts but dies before I can reach xmitter to throttle up or down.
Can't see carb with engine upright in plane (Venture 60) but could see fuel below engine in fuse.

Hobbsy,
Good idea! I had that problem with an old HB .61 PDP last year and after adjusting idle screw it runs great but I tried it on the Saito .80 and same results.
I have a NIB Saito .91 and I'm thinking about breaking it in and putting it in the Venture 60 and giving up on the Saito .80.
Thanks.
