Walbro or Tillotson Carb
I recently bought 2 used ZDZ80 Supers. One has a Tillotson carb and the other has a Walbro WJ-71. I want the best combination in the plane I am putting one of the engines in. Which carb should I use? I have a couple older ZDZ 80's with the Walbro WJ-71's and they run pretty good. Has anyone found the Tillotson to be an amazingly good carb? Is it far better than the Walbro?

Tillotson carbs have been around and used since before 1960 good carbs</p> |
RE: Walbro or Tillotson Carb
Tillotson carbs are now made in Ireland. they used to be made in the USA many years ago.
IMHO they are as good as Walbro and Zama but are not as common anymore. I have a couple chainsaws with Tillotson carbs and I have not had any trouble with them that I would not have had with a Walbro for the last 13 years. |
RE: Walbro or Tillotson Carb
Are rebuild kits as available as those for Walbro? Thanks.

RE: Walbro or Tillotson Carb
I rebuilt one of mine last year and got the repair kit at the local chainsaw dealer. He had it on the shelf.
I see them advetised on the internet all the time by various distributors Tillotson has a web site with charts like Walbro and Zama that lists all the Tillotson carbs, their setttings, and the pats numbers. http://www.tillotson.ie/ |

I don't understand what you don't understand?

RE: Walbro or Tillotson Carb
Some people complain that Tillotson carbs are more difficult to adjust than a similar sized Walbro. No first hand experience here with a Tillotson in an airplane but I have worked with several of them in saws many years ago and couldn't see any differences for that application.

My thought is...the brand of a carburatordoes not matter. If you get a good one in any brand...that what counts. Capt,nhttp://www.rcuniverse.com/forum/js/f.../thumbs_up.gif

RE: Walbro or Tillotson Carb
I am guessing you meant that you had the same problems with both.

RE: Walbro or Tillotson Carb
Tilotson carbs are fine.. Way way back a couple of manufacturers converting chainsaw motors were using the tillitson carbs that came with the powerheads they were buying.. These carbs had the RPM limiter circut start to kick in inflight and make the motor run erratic.. Once they figured out what was happening they started buying walbros cause they were cheaper instead of buying the correct Tilotson carb for what they were trying to do... This seemed to start some myth that walbros are better...

Have had 2 friends one with a 3w 106 and one with a ZDZ 80 both had terrible starting issues an tuning issues once running using a starter it would tune and run great... Shut it down it wont restart with out adjusting the tilitson carbs... Both got fed up bought a walbrough and none have had an issue since

Besides the Dolmar chainsaws with Tillotson carbs, I have a couple Stihl chainsaws with Tillotson carbs that I have never worked on.

RE: Walbro or Tillotson Carb
Sometimes the best carb for your engine is not the one supplied by the manufacturer, sometimes there is nothing wrong with the carb or make, but simply the venturi size does not suit the engines design.
I have swapped "bad carbs" onto another brand engine and ended up with a great running engine and more rpm than what was supplied by the manufacturer. I find its worth experimenting with diferent carb/engine set ups as the carb can make a huge difference to power output and how a motor runs. |
RE: Walbro or Tillotson Carb
I think it may be a good Idea sometime to start a new thread. Subject...Good Carb swaps !
