Exmark (Propane Mower) not starting

I recently purchased a used 60" Exmark propane powered mower. (Got a great deal on it). The problem is it is a PAIN to start. I got it started a few times but now it wont start at all. It has spark on both plugs. To even start it, you have to start it with propane off, then turn it on when it starts. But, like I said, now it wont even start! This is my first propane powered unit and I'm not familiar with these systems. It has a Kawasaki FH680V engine, 23HP.

Check valve clearances to see if they are in spec.

It may be not enough vacuum to open the propane valve. So find the vacuum line put ina tee and run line so you can suck on it to help. When it starts block the hose with golf tee. The valves can be adjusted or repaired to fix problem, kinda complicated.

We would advise you not to adjust anything. Please call Exmark Tech Support and ask for Joe at 402-223-6375.

It is mounted like you said. I am at a loss here! And the frustrating thing about all this is, here in Albuquerque, I cant find ANYONE who works on this type of unit! Not even the local Exmark dealer works on them!!!!! Tomorrow I guess I will try local forklift repair shops since alot of forklifts are propane powered. I just hope that they will be willing to work on it! I also might consider switching it to gas if it is going to be this much of a pain to get repairs and maintenance done to it!

You need to find out if this is a Metro conversion or from Exmark. There is a regulator that needs to be set at a certain PSI. If it is not correct, you're gonna have problems with it. All the units I've been involved with start easier than gas, no choke needed (you should'nt have a choke cable left anyways)
Go to www.metrolawn.com and see if thats what you got.
