I have a 83 venture. It has been sitting for a couple of years. I first removed the carbs and went through them. They was very nasty. The fuel dried and hardened into that dark brown almost black substance. I think I got all the passage ways clear. The diaphragms are a little wore out. They will work but looking for replacements. I put it all back together.
I have spark to all four plugs. I have fuel to carbs. I opened the drain screw on all four carbs, one at a time, to make sure the fuel pump was working. Got fuel out of all four drain lines on carbs. Tired the start engine. engine turns over but wont fire.
I decided to check the compression.
left front 85 psi
right front 120 psi
left rear 90 psi
right rear 90 psi
Will the engine fire with those three low psi's ???
What is a normal psi for a venture 1200 ???
I sprayed starter fluid down the right rear plug hole when
I had the plug out. I tried the start the engine and it fired once.
So, I know that cylinder will fire if it has a fuel source. I didn't try any of the other cylinders that way. The plugs don't smell like fuel and looks dry. I make have to go through the carbs again to see if these is any passage ways I missed.
Is there an accelerator pump on these carbs ???
Thank you,
