hey there,,hoping someone can help with a head scracther,,prochem blazer ticks over as normal but when you give it some throttle and block the vacuum slot it puts strain on the engine and it cuts out,,took air filter same thing,,no oil on the head so not sure if its the head gasket,,anyone with any ideas,,thanks
Needs more fuel when under load filter may be letting enough thru to idle but not enough under load I've had it happen to me before. Take the fuel line off at the motor after the fuel filter and make sure ur dumping plenty of fuel while the key is on and overide (if equipped) is in the overide position (safeties shut off the fuel pump) ... (put the fuel line in a gas jug while you do this so fuel doesn't go everywhere) if it isn't flowing you've narrowed your problem down to fuel wich is usually filter, fuel pump, or a bad or pinched gas line. Let us know if this doesn't fix it air cooled motors are pretty simple fuel, fire, air usually if you have these three things it will run like its supposed to. We'll get it figured out
I had this same problem years ago with a Prochem machine. Turn out to be a bad float switch in the waste tank, the vaccuum pressure was causing the switch to shut down machine. Try unplugging it. It took along time for someone to figure this out for me, hope this helps.
