All Things 288XP

[41FanForLife]

Question for the 288xp gurus or @PA Dan . Mike rebuilt my 288 after Duane's GTG. New seals,bearings, gaskets ,the whole deal. He went through the carb too. Pulled it out today to drop a few small pines for a friend. Saw sounds super powerful but when i laid it flat for my base cut on the notch it blubbered and sputtered pretty bad. Its a stock Tilly carb. Any ideas on which way to investigate this problem. Or should i be looking at a different carb? Thanks in advance for any and all advice.

Is it a limited Carb? I.E does it had a big brass plug threaded in the side of the carb with a slot in the top?

Was hot, then cool, now it’s hot again. So normal.
How’s about youinz?

That could be your problem. I think it is designed to let more fuel through when the vibrations reach a certain level and they can wear and dump in too much fuel too soon. In my experience 288's run much better with the later non-limited carbs. I am speaking from experience - I've rebuilt and run at least eight 288xps in the last 3 years....

Which model carbs are the later ones? I have the same carb for my 281 and we will try my carb to see if it solves the issue.

Can confirm.

I had a later one but it still had a fixed aux jet inside under the metering diaphragm. Couldn’t get it lean enough. Removed it and soldered it shut with intentions of drilling it out smaller. Ran it like that and it tuned at 1.25 turns out so I left it

I'll have a look later my friend, My Rattler 288 is a '97 model and definitely has the unlimited carb. The easiest way to check is that the unlimited version doesn't have that great big brass plug!

Mine's 95. I'll have a gander too.

Whats compression? Pull the muff and make sure piston is ok. If it is...then just get a fresh carb. Saves time and aggravation

Piston is good,fresh ring, and lots of compression

@Glock37 just did a total rebuild with fresh ring. I'm confident all that is in fantastic shape!

Latest 288 carb I have here is a Tilly HS-228C. I'll dig into it and see if it has the fixed auxiliary jet that Kevin is talking about.

What are we looking for? I don't see any big brass plug on the PTO side of carb.
Looks like Mine's a 97 too, not a 95.
