I would suggest that you start with the simplest test.That is check your compression.If it is to low your pump wont bring up enough gas thus needing lots of pulls to have enough gas to start your sled.You should have 120 to 130lbs for a good compression.Also try taking out your plugs and pouring in a couple tablespoons of gas in each and then see if it fires up .If it does then you know that you have a gas problem Good luck Dan
OK so your compression is good.Try putting gas in the jugs before cranking it and see if it start right away!If it does then your sure its a fuel problem.Also you said you check the lines ?Did you check your pulse line ?You might want to take your fuel pump apart also and put in a kit .Very inepensive and should be done every 3 to 4 years anyways.Good luck Dan
Catlover is right on. If you make every thing mentioned is right it should always start by the third pull. One more thing- always add 1/2oz. of isoprople per gal. gas. One drop of water can plug a jet.
It comes from the motor crankcase. Typically beneath one of the carburators (on multi carb motors). It runs from the motor crankcase to the fuel pump.
Trace the hoses from the fuel pump. There is one supply line (to tank). One line per carb (duh). One impulse line. That line runs direct to the motor.
It uses crankcase pressure to actuate the fuel pump diafram.
However, it is my opinion that if the impulse line is at fault, the engine would run way lean, and you would be looking for advice on rebuilding your top end, instead of just a sore arm.
Does it start, or want to start, any different with a brand new set of plugs?
Try this test to elminate a rich condition. Pull the plugs out before you go to bed, or work or school or whatever. Leave it sit for 8 to 12 hours with the plugs out. This will allow any excess fuel to evaperate for the combustion chamber and crank case.
Install a BRAND NEW set of plugs.
Attempt to start the engine WITHOUT the choke. Half a dozen pulls or so should do.
If it doesn't start or fire, try 1/2 choke. Give it another 1/2 dozen pulls.
Try this after you try the teaspoon of fuel down the spark plug holes.
crush, plugs are brand new, i'll have my neighbor help me with it
he use to own a jag like mine many years ago i'll print this
so he can look at it. or as jack wade from james bond goldeneye
hand me a sledge will ya jimbo. my neighbor said there
were no cracks
