RE: HELP
Here's 2 trucks I have that the engine pinch is worn out on.

Hopefully that's not it.
Here's a tuning guide I wrote, you will need to find the engine model and I'm sure you can get the factory settings for the carb online. If you need help finding the manual PM me.
To get it tuned, First get the engine fully warmed up!
Never tune a cold engine.
Start from factory settings on all needles. (Maybe 1/8 to 1/4 in on the HSN from factory.)
Be sure to set the idle gap as well as needles to factory settings before retuning from scratch.
Get your HSN set first.
Keep leaning the HSN 1/8 turn in at a time and watch the performance increase.
Making a couple top speed passes each time to let the engine get used to the new setting.
When you see a decrease in performance turn the HSN back out 1/8 to 1/4 turn to richen it back into the safe zone. Keep an eye on temps as well.
Good top speed and good trail of smoke at all speeds is what you want.
Then set the LSN.
You can do the pinch or punch test, or both.
PUNCH TEST-
Once you have the HSN set, engine warmed up.
Make a couple top speed passes and bring it in and let idle for 10- 15 seconds.
Then give it 3/4 to full throttle.
If is slow to take off and smokes alot you are too rich and need to start leaning the LSN.
If it takes off fast, rev's and dies, etc... it is too lean and you need to richen the LSN.
If it smokes and is slow taking off, start turning the LSN in 1/12 to 1/8 turn and again make a few passes to get it used to the new setting in between adjustments.
PINCH TEST-
Make a couple top speed passes, bring it in and pinch off the fuel line near the carb.
Start counting 1...2...3...
It should run for about 3 seconds before it revs and dies.
If it runs longer you need to lean the LSN.
If less than 3 seconds you need to richen the LSN.
Once you have good acceleration and still have smoke at all speeds you are done.
You may need to reset the idle on the carb once you are done tuning.
Weather always plays into your tuning and you will need to adjust the HSN for day to day conditions.
I.E.- colder weather requires more rich settings and vice versa.
I am just a basher and no expert so use this info at your own risk!

RE: HELP
Here's a good walkthru on how to seal your engine.
It's a good idea to seal your engine whether you have a problem or not.
Just gives piece of mind and eliminates future problems.
Feel free to rate my posts if they are helpful.
