CHECK SPARK FIRST, THE CLASSIC WAY FOR 100 YEARS GOOGLE HOW. 5MILLION HITS. i USE NEW TEST SPARK PLUG TO TEST SPARK. GROUND TO ENGINE BLOCK (METAL) IF GOOD , SPARK NEXT IS BAD FUEL OR EVEN THE AIR FILTER PACKED UP IN SAW DUST EASY AS PIE. OR CLOGGED FUEL FILTER FROM BAD FUEL AND LAST CLOGGED CARB FROM BAD FUEL OR AMAZING AS IT IS ALL 3 WRONG, FUEL DOWN. I ASSUMED COMPRESSION IS GOOD. HAND PULLED STATER . OR NOT USING CHOKE OR TOO MUCH.

I always start at 1 1/2 turns out and then with the saw running adjust as needed 1/4 turn at a time

try starting with both needles turned out one and a half turns, than fine tune from there. Make sure you are on the rich side of both when finished.

cheapest way is a new fuel tank from e-bay that has it all installed you can remove the rubber grommet around the lines to get it out then get a new filter to push on the line BUT will it be cost effective against what can be obtained from e-bay

i have a 4620 poulan that had the same problem. use it for 10 minutes, spend 15 minutes reinstalling the chain. i sent poulan an email threatening to sue them and they decided to send me the parts to change it over to the old style for free. try poulan.com

Find the air/fuel mixture screw to adjust. Clock wise to lean Counter clock wise to richen

It is important if you have changed the fuel lines that they are reconnected correctly, the bubble is a purge not a primer, so it pulls fuel from the carb and dumps back to the tank, on the back of the bubble there are two connections, one long one short, the long connection is the pressure side so goes back to the tank, the short one is the suction side so this goes to the carb connection nearest to the metering cover ( the one held with four screws) the fuel hose from the tank with the filter on the end goes to the connection on the carb nearest to the pump cover (held with a single centre screw) if you have not already done so replace the fuel filter in the tank.

The 2150 has a remote primer, so there will be three pipes, the pipe coming from the fuel tank with the fuel filter on the end is the main fuel tube, this fits to the connection on the carb nearest to the pump cover on the carb ( alluminium cover held with a single screw ) the other connection on the carb has a pipe to the shorter of the two connections on the back of the primer ( suction side ) the longer connection on the back of the primer ( pressure side ) has a pipe back to the fuel tank, so the primer pulls fuel from the tank, into the bulb, and dumps it back to the tank, it does not push fuel into the carb, this way you can depress the bulb as many times as you like without flooding the engine.

Remove the 2 screws "1" and "2" to remove the muffler.

Anytime there is a difference in the "Type" something was changed on the product. To determine all of the changes in all types would take some time going through each of the part's lists.

The chain could be stretching. Are you using a good quality bar and chain lube? Never use old motor oil. Once the chain has jumped several times it may be bent. Properly adjust the chain and keep an eye on it while using. start with a new bar and chain and watch the tension. You can also replace the tool less cover with a standard cover for about $25

Yes, anything can be fixed, well almost. I've had the same problem with small engines. Start by taking the plastics off, you should be able to find the rest of the fuel line that goes to the primer bulb. Then from the bulb to the carb. You need to the correct size fuel line and replace it and put on a new filter. Just remember, if it damaged the lines, the carb needs to be removed and soaked or replaced. To keep from going through this again I recommend the pre mix two cycle fuel, just make sure the ratio is correct, chainsaws are usually 50:1 and other small engines run 40:1

take it back for a warranty service check is the stop switch been activated

It's possible the brake is on. Try pushing the brake forward then pulling it back until you hear it click. Then try cranking it again.
