Soak the carb body in fuel for a day or so and then try to blow air through the small passageways. I suspect they are all clogged with old oil and other crap.

This is something else I had to do the last owner had left fuel in the needle socket of the carb and it turned green and dryed. When I put the engine back in use the the dryed green fuel came loose in the needle socket an would partially block the holes. I used my set of micro drills to clean out the green crap. I used the drillbits to push the crap out of the way, not to drill out the green crap, but by placing the opposite end of the drill bit into the passages. Don't use the flute side of the drill only the side that normally goes into the chuck of the drill. It ran better at full throttle but eventually I ran into the same problem you are having.

Can you post pics of you liner? I think that would help a bit. Here's a liner I drew in CAD. All liner's exhaust ports will be closest to the head.

Not having the middle bar on the exhaust port is ok for ABC/ABN engines. It is needed on a ringed engine two keep the ring from popping into the exh port. 

You may have an old Performance Specialties piston and liner in it or someone ground off the middle bar. That would not be causing the problem you're having the though. I still think you have a bad gasket somewhere or a clog. I'll have to check my 60 FR becuase I'm thinking the one I have does not have the middle bar either.

Have you checked the rear cover gasket? Maybe someone used gasket sealant and it now has sprung a leak. It is deffinitly not getting fuel into the engine which leads me to think the needle socket is clogged or the pressure system has is be the cause e.g. cracked diaphram or ????? Contaminated glow plug maybe?

Hey Bryan, nice job on the CAD drawing!!


I did a complete 3d cad drawing of an OS Max 61 FSR/VF liner in Autocad. I keep getting emails from a company that claims $95 for a one run CNC aluminum part. So next time I have a spare $95 bucks to gamble with I might send them the cad file to see what they can do. The 61SF/RF longstroke liner has the same port setup in the same locations. The timing is different do it being a long stroke but if you place the FSR liner in a SF case the ports line up in the same locations.

Idea was to maybe play around with plating it or getting a CNC ringed piston to fit it as well. Pipe dreams at this point, but ya never know.

Bryan

Status: online 		Paul,

I was a YS guy with the short strokes.. It was nice to buy 4 of them and they would all set up the same... But when they changed metals and went to the long stroke it was hard to get 4 and have them all run anywhere close to each other... That is when I switched to the OS... your right they do not have the RPM's as a short YS, but they do have stump pulling power... If I was to go for RPM'S and good clean runs right now I think I would pick the Rossi that alot are running in the SE. The OPS gold head was one of my favorites also, ran those on my XLT in the North East.

I have collected several OS's pumped RE engines and yes I even have a YS Long Stroke.. but will always go to the OS first..

Starting to get cool in the South East now, so building season is close.. How is it up your way Paul ?

Scott
