Engine problems...need help
I am currently trying to revive a 94 750 that has been parked for 4 years. So far, flushed cooling system, changed oil and filter, cleaned air filters, spark plugs and caps, new westco battery. All plugs are sparking, compression is very good.
Existing problems are: possible problem with the choke cable mentioned by previous owner, fuel valve on bottom of tank flows even with no suction on it. small radiator hose leak...
Main problem...engine starts, idle well at 1200/1500 rpm, although the rpms seem to rise and fall every few seconds (another one to sort out). It runs like this for about 5 to 7 minutes and then dies out. After this, it will start, but will only run for about 5 seconds. During both of these runs, I have to leave the choke all the way down, and if i try to give it any gas, it dies. I plan on rebuilding the fuel valve and have a new choke cable on order. Any other ideas would be appreciated. Do I need to mess with the mixture any? thanks in advance for any help.
