I think both of these say not to mix at less than 50:1.
Not quite true, both manufacturers recommend 50:1 for their equipment but that has nothing to do with the oil itself being mixed at other ratios for other applications. Notice the first sentence in bold at the top on the back of the Stihl container.
Now see what you did.LOL

jody -
what is 7800+ ??
is that 7850 ? 7900 orover 8000??

to me it either does xxx rpm or it doesnt.

Apparently you've only run one engine once.

If you run as many engines as I do you would know that every engine doesn't spin the same prop at exactly the same RPM, and that the same engine on different days and at different times of the day will turn different numbers based on atmospheric conditions. My statement that it will turn a prop XXXX number of RPMs is a minimum figure based on the performance of several engines run at different times and in different conditions at my location. The engines in my sample size have all turned those props mentioned at the numbers I posted minimum to 100 RPM more.
OH REALLY?!?!?!?!?!?!
no need to act smart- we all know, no-one else has ever run as many engines as you!
if you'd simply stated 7800 rpm it would be a given that each and every engine / day / user would get different figures. I was just asking what you defined by the '+' sign
i didnt ask if you had done 9000rpm, just asking clarification of what can be expected, which is exactly what you have now stated - 7800-7900 rpm is likely! simple answer really, dont know why the smart remark.
I guess if I asked you the price of an engine you'd also say $150+

Nope, price doesn't change with atmospheric conditions, it's the same all day everyday.

The Walbro WT759 carb that comes with the MT-35 engine has no ball and spring detent to hold the choke in the closed or open position. Does the WT805 carb have one or is this a feature that is used only on carbs for larger engines?.
Is anyone using some kind of substitute for the ball and spring?

A little off topic but since I see rpm's back on the post I will ask this... Is the dle 55 or any other gas engine have a recommended heat operating range?

The carbs I put on the MT35 have a detent choke, they don't come that way but I modify them with the correct Walbro parts. I can also sell the parts for those that want to convert their high idle choke system to the detent type.

There is no published temp range that I know of for the engines we use, I think mainly this is because 99.9% of people would not invest in the proper equipment to be able to monitor it accurately, an infrared temp gun won't cut it. But to answer the question, anything less than about 190F is stone cold, average temp over the duration of a flight should be 250-280F with max highs for very short periods around 300-310F. Temps consistently exceeding 300F as measured on the outside of the cylinder, for more than a few seconds will do damage that is accumulative in nature.

I'm trying to learn and understand. Is the detent choke the arm that the choke cover is attached to? It also has an extension to turn the choke plate? See photo.

Weather is great here for flying.We have had a lot of rain for Wy.Snowed three feet in the mountains a couple of weeks ago.Flooding in places,also almost unheard of in Wy. We are about 500 ft above the rtiver if it floods here will need to build a ark.
Put about three hours on two of the DL 30s over the weekend. I can not believe the power of these little engines.I have sold all of my ST and weed eater engines and am changing to the DL 30s.Have five of them now. All side carbs and all run fine.
Am going into the Billings MT hospital next week. They are going to replace my right leg main artery with Gortex. I already have three Gortex grafrts.now.First have to have a heart cath.Maybe stint or rotor router.Sorry off subject.
Sent a piston and cyl for DL 30 down to ring man.I can not remember his name.Known him for years.My 30s are getting better compression all the time.

Hello Bill, sure glad to hear from you. Thanks for sending Frank Bowmansome DLE parts so he can make some custom rings. That will be great!!! Good to hear you are getting some flying in....that is what I got to do. We will be praying all goes well on the plumbing job & that you can get back to flying soon. I bet the serial number on my 30cc DLE is close to one of yours. #C 01052 Best Regards Capt,n

Hope the surgery goes well. Mustang's fly-in is this weekend in Billings. Hoping to be there for a few hours on Saturday. Stop out and visit if you're feeling better by then.

Anybody try the MT on a pipe yet?  I hope to give it a spin with my ES composite pipe tomorrow.

Got it ran on the bench today, finally.   Started easy, idled solid, and it pulled my test table across the garage floor.  My test table is a 8 foot banquet table.  It blew a bunch of stuff off my work bench including my brand new cowl.  Ohh... that made me mad.   Nice crack in it now.  Strong engine.  I didn't get to the pipe today... kids keeping me busy.

Got it ran on the pipe and wow. I ran a 18x6 prop and I got up to 8000 and it blew the pipe off.
You didn't specify which brand of 18x6 prop that you used on your MT-35 with the ES composite pipe but it sounds a little lacking when compared to the smaller MVVS 26cc which can turn an APC 18x6W at 8800 RPM on the standard muffled MVVS aluminum pipe. The 8800 RPM was achieved with a stock out-of-the-box 26cc with none of the hop-up mods that can be found on the Web.
Neither one of us may be giving enough details here to explain why such is the case but one factor may be that the MVVS was designed from the beginning to be a high performance model airplane engine while the MT-35 may be a very nice looking garden tool engine. I remember from the days of fast pattern flying that some engine manufacturers designed their engines with port timings that favored tuned pipes.
Is your pipe the correct size for a 35cc engine?

I have read about the MVVS 26cc. Sounds like a great motor. I didn't get a chance to get a reading at wide open throttle. It blew my pipe off at 8000. I did get a reading today. It spun the 18x6 Xoar Beachwood at 9690. It would be probably be a better to keep the rpms in the mid 8000's. I fly mostly pattern and the 18x10 might be a good choice. I did test the APC 18.1x10 pattern prop. Loaded the motor more of course. It spun at 84 something then saged and I ran out of time and didn't tune it.
